(infra): Support Querying Delegated Nostr Events (NIP-26)

Ticket(s) / Related Merge Requests

Issue: #2414 (closed)

Summary of Changes

This MR allows for querying delegated Nostr events, so that when requesting for an author's public key we will also check for events with this key in the delegation tag.

Testing Considerations

Try creating a NIP-01 REQ event asking for a user-managed public key. Assuming that delegation is configured, you should see your Minds posts.
